I have a goal to do a DNA comparison test this month. There are two individuals I want to test so that I can find out if they descend from the same male ancestor – one is black (Person A) and one is white (Person B). My primary genealogical research leads me to believe there is a strong possibility they both descend from a male white male who lived from 1798-1881. I want to compare their Y chromosome DNA. My dilemma is this — which DNA testing service should I use?
Here are the considerations:
a) 23andMe – I have a free 23andMe testing kit I can use for Person A. I ordered it for him as part of the Roots into the Future Initiative. I would love to use this b/c the test is free. For Person B, I would then order another 23andMe test for him and pay for that one ($99). The benefit of having them both in 23andMe is that I could compare both Y-DNA and autosomal DNA. I know that 23andMe will tell me if their Y chromosomes are the same or not — is it as good as what I could learn from FamilyTree DNA?
b) FamilyTree DNA — is my other option – they are so well-known for the Y marker tests. Since I have the kit for Person A already, I could then pay $50 to submit his DNA to FamilyTree DNA. Then, I would purchase the 37-marker yDNA test for Person B. The benefit of using FamilyTree DNA is that if Person A turns out not to be related to Person B, then there would be other surnames in the database that *may* come us as matches.
Which would you use in this situation and why?
Update 11:30pm — I have my answer! FTDNA it is. Turns out that 23andMe does not test markers on the Y Chromosome like I thought they did so I’ll be ordering the 37 marker test for both men. Thanks everyone!
